Objective / Background
We seek to align the pre-operative CT with the intra-operative MRI.
Keywords
MRI, CT, IGT, intra-operative, liver, cryoablation, change detection, non-rigid registration
Input Data
reference/fixed : intra-op MRI, 0.78 x 0.78 x 2.5 mm axial, RAS orientation.
moving: pr-op CT, 0.95 x 0.95 x 5 mm voxel size, axial, RAS orientation.
Methods
Registration Results

Download
- download input image data (Input Data, NRRD images, zip file xx MB)
- download registration parameter presets file (.mrml file 20 kB)
- download guided tutorial (PowerPoint, xx MB)
- download full tutorial set (Input Data, presets, results, tutorial, zip file xx MB)
Link to User Guide: How to Load/Save Registration Parameter Presets
Discussion: Registration Challenges
- large differences in FOV
- strong differences in image contrast between MRI & CT
- contrast enhancement and pathology and treatment changes cause additional differences in image content
- we have strongly anisotropic voxel sizes with much less through-plane resolution
